AC Milan did the unthinkable on Wednesday—they beat Barcelona 2-0 and kept a clean sheet in the process.

The pitch is as wide as regulations allow it to be, the surface zippier, wetter and classier than the San Siro's purposefully barren outlook.
Another onslaught beckons, but after the first leg, why can't the Rossoneri repeat their heroics?
